I'm Interested In Understanding Types Of Heart Rhythms. Is This

I'm interested in understanding types of heart rhythms. Is this something I can ask? Im currently seeing cardiologist for some extra heart beats and Im going to do a holter monitor. I have a history of PVCs. But there is a new rhythm that I am experiencing and I only want to know what possible type of rhythm it is. I am a medical assistant instructor and know a bit about A&P. When I was experiencing some flutters I listened with my stethoscope and this is what I herd. I here a da-dump, da-dump,
da-da-da-da-dump, da-dump da-dump. ect. SO im basically having 2 to 3 extra rapid beats in between a normal beat. My cardiologist didnt tell me what type of beat this could be? Can you give me an explanation.
